Patent DE-3801707-A1 (DE)
Title: Insulation measure against the longitudinal conduction of sound in structural parts
Inventor: MANTEL JUVAL DR ING
IPC: F16L55/033
Filed: 1988-01-21
Abstract: In interior and exterior walls, particularly those whose weight per unit area is less than 250 kg/m<2>, the sound is conducted longitudinally as structure-borne sound, it being very difficult to eliminate this sound. The solution according to the invention consists in the fact that the walls are provided with joints which do not, however, reduce the stability of the walls to any great extent, but do eliminate longitudinal conduction of sound. A joint-forming rail pair is normally designed as a rectilinear rail, which is introduced vertically (in order to prevent door-closing noises), but also rectilinearly vertically on a lintel along with correct dimensioning of the device. However, it is also possible, for the purpose of preventing system noises, particularly installation noises, to use the measure where the rails are formed to produce a circle or circle part which can be introduced into the wall around a pipe lead-through (fitting fastening) or duct lead-through (ventilation duct, fire shutter), the rails forming a square.

Patent DE-3814765-A1 (DE)
Inventor: FUCHS FRANZ
IPC: F16K31/10
Filed: 1988-04-30
Abstract: A valve for sealing a conduit under pressure has an armature (12) cooperating with two springs, a permanent magnet, and a solenoid coil. The force of the permanent magnet is used to cock a spring and thereby stored primarily as a spring force when the valve is in any of its two end positions. THe spring force is slightly smaller than the permanent magnetic force of the permanent magnet, and this slightly smaller spring force is effective on a valve stem through a sleeve in a direction opposite to that of the permanent magnetic force. The permanent magnetic force is, for example, stored in a Belleville spring and additionally in a helical or conical spring which provides an extra valve biasing force. In order to open the valve, the solenoid coil (9) of an electromagnet is energized to counteract the force of the permanent magnet to an extent slightly below the stored spring force. Thus, this valve is capable of having a monostable or a bistable characteristic, depending on the adjustment of the spring force with the aid of an adjustment ring engaging a threading on the valve stem.

Title: Sensor for the detection of irradiation
Inventor: NOLTING PETER DIPL ING
IPC: B60H1/00
Filed: 1988-06-28
Abstract: In a sensor (10) for the detection of solar irradiation (insolation) into a passenger compartment of a motor vehicle, at least two photodiodes (12, 13), separated optically from each other, are arranged so that each photodiode (12, 13) determines the light irradiation from a different direction.

Title: Method for operating an axle of a control or regulating element of an apparatus
Inventor: MADERSBACHER HUBERT
IPC: F16D3/04
Filed: 1988-08-31
Abstract: The invention relates to a rotary element for actuating an axle of a control or regulating element of an apparatus, which rotary element is provided with a device for compensating an offset between the axle and the bore accommodating the latter in the rotary element. The object is to accommodate this so-called axle compensation within an axially restricted space in the rotary element itself. This is achieved by virtue of the fact that the rotary element (1, 101) consists of three parts, namely a rotary element (4, 104) proper, rotatably mounted in the apparatus casing (2, 102), a guide element (5, 105) accommodating the axle (6) of the control or regulating element, and a clutch element (7, 107) which is inserted between the rotary element (4, 104) proper and the guide element (5, 105) and by means of which the rotary motion of the rotary element (4, 104) proper can be transmitted to the axle (6) of the control or regulating element but is arranged with clearance within a circular-cylindrical outer shell (10, 110) of the rotary element (4, 104) proper, with the result that a radial offset and/or tilt of the clutch element (7, 107) in relation to the rotary element (4, 104) proper and/or the guide element (5, 105) is possible. <IMAGE>

Title: Flat-bed screen printing machine for printing of electric circuit boards
Inventor: GETZSCHMANN HANS-JOACHIM
IPC: H05K3/12
Filed: 1989-02-17
Abstract: A flat-bed screen printing machine is described for the printing of electric circuit boards which are provided with an electrically conducting layer and are to be printed with two print images. In order to move the printing table plate (23) which is arranged on the printing table, a control arrangement (43, 45, 47) is provided, the latter having electronic cameras (13a, 13b) which, after a circuit board (20) has been placed on the printing table plate (23), record the actual position of reference marks (41, 51) on the circuit boards (20). The control device (43, 45, 47) then compares the actual position of the reference marks (41, 51) with a previously determined and stored desired position, in which both print images are aligned with each other, and derives from the comparison a control signal which triggers stepped motors (25a, 25b, 25c) and guides the printing table plate (23) on the carriage (24) until the actual position of the reference marks (41, 51) on the circuit board (20) agrees with the previously determined desired position. <IMAGE>

Title: Storage and feed mechanism for rod material on notching machine - has several stacked inclined surfaces with adjustable side walls forming magazine
Inventor: ZWETKO ZWETKOW
IPC: B23Q7/00
Filed: 1989-07-24
Abstract: The invention concerns a storage- and feed mechanism for round rod material for notching machines. The mechanism is attached to the notching machine and operates as follows: When the notching machine is started up the ram (42) lifts the plunger (32) against the force of spring (40) and hereby, by intermediary of stub (18) guided in slot (16), the lever (17). As a result rail (15) is also lifted, increasing the passage between rails (15) and (19) is increased allowing motion of rods towards the guide slot (24) where the rods may enter only one by one. The lowermost rod is positioned by jaws (29) and the machining process starts. At the same time a mechanism on the  notching machine returns the plunger (32) to its original position and the sequence is repeated when the machining of the rod is completed. ADVANTAGE - The design, in comparison with previous design does not need its own drive and supplying several machines from one feed mechanism is possible.
